Abstract
The invention provides a kind of liquid section coal sulfur-fixing agent.Comprise cerous nitrate or holmium nitrate, copper sulfate or cupric nitrate, potassium permanganate or potassium ferrate, sodium alkyl benzene sulfonate or polyvinylpyrrolidone, deionized water.The present invention reaches saving coal, Gu sulphur environmental protection and the effect do not had a negative impact to combustion equipment and environment by reducing activation energy.In addition, fluid additive overcomes again the shortcoming of solid additive, easy to operate, and spraying evenly.
Description
Technical field
The present invention relates to a kind of coal-saving additive, particularly relate to a kind of liquid section coal sulfur-fixing agent.
Background technology
Along with sustain economic develops rapidly, population constantly increases, and coal consumption amount is year by year to increase considerably.Coal combustion is the major way of coal utilization, and China's energy structure is mainly based on coal, and the coal about more than 20 hundred million tons every year for directly burning, causes severe contamination to environment.How to utilize resource in sum efficiently and decreasing pollution to greatest extent, become the vital task of pendulum in face of us.
Current coal-saving sulfur-solidifying agent is mainly divided into liquid and solid two kinds.There are some drawbacks in existing solid additive in the use in large-sized boiler power plant, cement mill, solid additive in use needs to use forklift to mix evenly in coal charge field, if large type coal field, this work is quite heavy, need increase larger cost and be easy to cause uneven mixing, use inconvenience, add uneven.
Summary of the invention
Object of the present invention is exactly defect for above-mentioned existence and provides a kind of liquid section coal sulfur-fixing agent.Burning of coal is the process of a heat absorption heat release, comprises the intensification of the precipitation of moisture content in coal, the precipitation of volatile matter, volatile combustion, coal, absorbs the activation energy needed for burning.The burning of coal.Although whole process intersects to carry out, cannot separate completely, the wherein precipitation of volatile matter, coal heat up and absorb the activation energy needed for burning, are endothermic processes.The burning of coal burning, volatile matter is exothermic process.When activation energy reduces, in-fighting reduces, and the coal-fired actual heat be utilized adds, and popular saying has been exactly the calorific value height of coal.The present invention reaches saving coal, Gu sulphur environmental protection and the effect do not had a negative impact to combustion equipment and environment by reducing activation energy.In addition, fluid additive overcomes again the shortcoming that solid adds, and a needs adds a powerful spray equipment on conveying coal conveyor and spray flux is proportional with upper coal amount, and easy to operate efficiency is high, and spraying is even.
A kind of liquid section coal sulfur-fixing agent technical scheme of the present invention is: comprise cerous nitrate or holmium nitrate, copper sulfate or cupric nitrate, potassium permanganate or potassium ferrate, sodium alkyl benzene sulfonate or polyvinylpyrrolidone, deionized water.
The alkyl that described alkyl benzene sulphonate (ABS) is received is C
12-C
20.
Be grouped into by following one-tenth by mass percentage: cerous nitrate or holmium nitrate 0.5-2%, copper sulfate or cupric nitrate 2-8%, potassium permanganate or potassium ferrate 1-5%, sodium alkyl benzene sulfonate or polyvinylpyrrolidone 2-6%, surplus is deionized water.Above-mentioned raw materials is added in the deionized water of charging capacity successively, stirs 1 hour.Wherein alkyl benzene sulphonate (ABS) is received and is preferably Sodium dodecylbenzene sulfonate.
Be grouped into by following one-tenth by mass percentage: cerous nitrate 0.5%, copper sulfate 5%, potassium ferrate 2%, Sodium dodecylbenzene sulfonate 2%, deionized water surplus.Above-mentioned raw materials is added in the deionized water of charging capacity successively, stirs 1 hour.
This liquid section coal sulfur-fixing agent is in use preferably 1:2000-4000 in mass ratio with the blending ratio of coal.
This liquid section coal sulfur-fixing agent is in use preferably 1:3000 in mass ratio with the blending ratio of coal.
Beneficial effect of the present invention is: this liquid section coal sulfur-fixing agent is easy to operate in the use in large-sized boiler power plant, cement mill, and spraying evenly.In described copper sulfate or the cupric ion of cupric nitrate be in complexing steady state and play katalysis, holmium nitrate or cerous nitrate can reduce burning of coal activation energy, play promoting catalysis.The major ingredient playing degradation agents effect is potassium ferrate or potassium permanganate.That plays dispersion agent effect is mainly cats product, nonionogenic tenside as polyvinylpyrrolidone or Sodium dodecylbenzene sulfonate.This liquid section coal sulfur-fixing agent not only makes coal Thorough combustion, and can the solid sulphur of environmental protection.Sulfur-fixing rate is also high than prior art.Through on probation, the present invention reduces burning of coal activation energy, to saving coals from boiler more than 5%, Gu sulphur reaches 40-60%.
